I posted this under the power supply/case forum, but thought that I would repost it here for those of you that may not frequent that forum as I would like your input as well.
Going to be building a pc soon. either q6600 or e8400 OC'ed. 8800GTS card.
So, for like $5 more can go from the 550W to the 650W power supply. I probably don't need more than the 550W, but for just $5 more wondering if I should just go ahead and get the 650W.
Cooler Master makes great cases ... buy their PSUs don't share that reputation. 550W is good for a one graphics card system.
Unless you plan on doing SLI but 650W might be a bit slim for that too.

Be sure to read the newegg buyer feedback reviews. Ignore the good reviews, just read the ones rated at 1 or 2. You want to know if it's just noobs whinning or if there's actually something wrong with it.
Think I will prob go with the $70 550W from buy.com. free shipping too. I might would look at the 650 harder if I was going to SLI or something because of the multiple rails. But, I don't plan to SLI.
^...For dual GPU SLI 550W is quite sufficient...so don't worry, 550VX is a great buy.
I'd rather not have 2x 8800GTS( 2 x 150W max) and an OCed quadcore(120W+) on a 550W PSU. Maybe I'm silly but it'd be running close to the limit and that's a bad idea even for a high quality unit like the Corsair. Just my thoughts.

Dagger, CoolerMaster PSUs are considered Tire 4/5 (except the higher end ones ie 700W which are ~Tire 3).
Lol, nice chart. It's a wonder manufacturers didn't sue those guys for defamation, considering how they list brands like that.
But yeah, I have no idea what brand is good or not. Listen to people who do.
Looking at that, mine is on low tier 4, but all rails output is rock solid on stress. Plus, it haven't got a single bad buyer review on Newegg, only 4 and 5s on a scale of 1-5. I wanted to buy brand name first, but saw the price, and then the good reviews, and considering newegg's return policy, decided to go for the bargain instead.
How scientific is that chart? How big a cross sample for each model of each brand do they test? It should be at least 500+ per model to be statistically significant.
Btw, just noticed something. On the psu, it says "Zumax" with "epower" only in the fine print. Maybe they saw the chart and tried to ditch the bum rep?
If Ultra's guys saw that chart they'd sue alright...
They sue everybody. Then they take 350W hardware, put a 600W sticker on it and sell it for $100+.
You can't go wrong with that chart IMO. An Enermax Galaxy dies from time to time. But 10 minutes before it dies it still offers 99.9% accurate voltages.
And it doesn't take a $350 motherboard with it when it goes.

For the most part the brands are listed in alphabetical order within each tier. The order within the tier has no significance. I noticed that you didn't list the Brand of PSU in your sig, are you embarrassed? Maybe you should be looking at a new PSU as well. I guess that's like the blind leading the blind.

Don't you think that expecting testing on 500+ PSUs of each type is ludicrous. They test and or dissect the PSUs to determine what components e.g., capacitors etc. are used and the design of the PSU itself. I'm sure they get their data elsewhere as well. The list should be used as a guide. If your PSU is a tier 4 or 5 it is probably junk.

Actually, the current psu is a replacement for this one, which keeps crashing my new rig. http://www.newegg.com/Product/Prod [...] 6817194004 After monitoring output, it's clear. Output voltage fluctuates far too much. No wonder. I purchased this after some guy online recommended this exact model. Ignored some of the... rather humbling reviews it got on newegg because I thought they were just noobs whinning. After getting burned on that, I returned it, got the first bargain listed, and was pleasantly surprised with the rock stable output even on high stress.
Looking at the chart, it's on tier 2.
Not saying it's bad. Surely I just got a bad apple. You really should read the user reviews though. Hey, at least the bad apple I got didn't explode like that poor sob who wrote one of the reviews.
Never had the chance to handle a Liberty(I guess I should be happy about that). INFINITIs are quite good
http://www.newegg.com/Product/Prod [...] 6817194021 Installed two with no issues. I had a Galaxy 850W die on me about one hour into my friend's build (15 minutes after installing Windows (we checked the voltages a few minutes before that and they didn't move at all). 2 reboots later it just dies. No smoke. No fire. Nothing. The replacement unit still works 1 year later and powers a nice little WS with 8HDDs.

I don't know if it's the pictures on newegg but it looks like it's been put together with caveman tools. Look at the gaps in the metal casing!
Those cables look like you could kill someone with them. The rear voltage switch is so 1995 ... what's it for ?
That gap is the width of the cross bars that held the fan guard in place. It can't be helped. That voltage switch is so it can be used in Europe... and Asia... and everywhere else other than US.
That's a Topower unit. I couldn't find any reviews on it. I noticed what I assume is yours that said

...recommended models from what they considered "good" brands, which cost around $200 for a 500 watt model with around 40amps total on 12v rails. review on Newegg that stated
That doesn't make sense because the Silencer 610 has been only $119 for at least a few months.
Since you are not loading the ePower very heavily, maybe it will work out good for you, I hope so.
... what's it for ?
