Need a psu

Post#1 » Wed Apr 29, 2009 3:32 am

My psu has been on it's way our for a few months now. I just started getting random shuht downs, and my case fans are spinning very slow. I want another modular psu, I'm having trouble justifying $120 right now for this Corsair:
http://www.newegg.com/Product/Product.a ... 6817139001.

Thoughts on these?

Anything else similar in price I should look at? Is the Corsair that much better that I should just spend the extra $$? With my psu acting up the way it is, am I in danger of frying my cpu, vid card, etc?

the big difference is efficiency. efficiency is how cool your psu runs, and how much energy you use (depends if you pay for electricity if you care). hotter usually equals louder.

of the ones you have listed, i would recomend the antec (free shipping saves you like 10 bucks on a psu btw)

modular is what drives the price up. i will be the first one to say that the power supply is not something to skimp on, ever.

if modular is the most important thing, questoins.

what is your graphics card? how many hard drives, fans, disc drives etc.
what motherboard?
what cpu?

is a very good power supply, and im 98% certian the 430w will be enough. i have the non modular version of this psu powering my main rig. (and just a hint, seasonic is the oem for corsair)

if you need more juice (which i highly doubt) there is a 500w versoin thats 92 bucks

http://www.newegg.com/Product/Product.a ... 6817171035

is also a good psu.

lemme know what your running, and i'll let you know how much power you need

I'm currently running an Athlon 64 x2 6000+ and an nvidia 9800gt, 2 hard drives, 3 case fans. I will most likely be building a new system this summer, and once am3 boards with sli come out I will probably pick up a second 9800gt for my new system, so I want my psu to be be able to handle that.

so, 9800gt's sli?

i'll give my lil rant about how for the same money (about 100 bucks) you can buy another 9800gt, you will be able to buy a graphics card that does at least the same if not better than the 9800gt's in SLI

ok, so for SLI ing 2 9800gt the 430w psu will probably be borderline. i have a useful tool i can use at home to calculate what you'll need from any given system.

also, do you overclock? do you plan to overclock?

overclocking is more power, and also requires a more stable psu. (all of the psu's i've recommended are very stable)

My current system is oc'd from 3ghz stock to 3.15, but the windsor core AMDs didn't oc that well. If I end up going with a phenom 2, I'd like to push what is possible with air cooling.

antec has a good reputation for PSUs.

if your planning on building a new rig in the summer, i'd hold off on getting a new psu until its necessary. keep an eye on the corsair 520 (which has been one of the best psu's to get for the last 3 years), see if they have a special or something in the next month or 2.

and i found some insight. the 9800gt, is nearly identical to the 8800gt, just uses a touch less power. 108w under max load. that is 9a at 12v. so 2 of them gives you 18 amps on 12v. if your cpu is rated at 125w, (phenom II quad) 10.5 more amps, so we are at 29 amps minimum on the 12v rail will be sufficient. which is 348w on the 12v rail (or rails). those are the 12v devices.

http://www.tomshardware.com/reviews/Sys ... 62-10.html

is a link where tomshardware ran an overclocked 8800gt SLI system on a 400w psu.
just note that it is a silverstone psu, which, they are one of the top companies for psu's (corsair and antec are up there too). a quality psu that has ample 12v power for your cpu and gpu(s) will power your system.

mmm not modular :(

if you don't want a modular psu grab
http://www.newegg.com/Product/Product.a ... 6817703015

probably the best psu under 100 bucks, period. 35amps on the 12v rail, might as well be a supermodel for your video cards. and it will power your next 4 computers. (so long they don't make drastic changes to power standards, liek they still use 12v 5v 3.3v etc)

i have one, and i am more than impressed with the quality of the unit. no, they arn't paying me (i wish). you can tell the thing means business from the get go. however, the corsair psu internals are almost identical to this ones. to each their own. 80 bucks +shipping is not bad at all (when i bought it i got it shipped to my door for 65... hoooray sales at newegg!)

ok im drooling, i'll stop now

I'll see if my current psu can hold out for another month or two. I'm this close to pulling the trigger on a new rig. My federal work study runs out next week, I just need to know I will have a job this summer before I spend the money.

my advice is to wait and see how long till you build a new rig to think about your psu. if a new rig, start from scratch with shiney psu in your budget. if not, go the upgrade route.

also, going for the tip to SLI your gpu's i would say no on that. annother 9800gt would run you about 120 bucks. thats assuming you find one, seeing as they are phasing that out and calling it a gts250 (or 240 i forget). those may/maynot sli with a 9800gt eventhough they are almost the same board. a $130 4850 will give you similar performance to 980gt's in sli so long as your at 1920x1200 and under (if your budget is an issue, im guessing 99.999% chance this is the case...)

my 2c, take it as you will.

I don't care about modular or non-modular. I had a modular ABS Tagan 700 watt PSU in my old computer and by the time I was done plugging everything up, the only thing I wasn't using was the 2nd PCI-E cable.

personally i don't like modular. just one more thing in the power line to go wrong, or for inneficiencies to occur, or voltage drops... etc. and unless you are buying a 1000w psu that looks like 5 squids glued together.... my opinion is modular is a marketing idea to sell the product for 25% more wile incuring a cost that is 1 or 2% more tops. i like it if i was selling you the stuff.
