If you overload your PSU, then it should just shut off, no damage. If it's faulty, then you stand the same chance of damaging your hardware with a low OR high load (again, a good PSU shouldn't take out anything). There is also nothing worng with running a PSU at full load either. This whole "don't ever run your PSU at full load" and "keep it below 80% capacity for maximum lifespan" thing is FUD.

FYI, 650w will still be enough for most things in 4 years time, power consumption is decreasing with performance increases. And it's not like everything will be SLIing ultra high end cards in 4 years time, there will always be a place for mid range stuff.

Plenty of people on here don't overclock...

Yeah, especially when modular PSU's come into play.... the only decent (or decently priced) ones usually start at 650w+.

I agree. Many people here keep claiming to get higher wattages so that we can be future proof'd, but when you get like 1000 watts, that is going into like tri/quad sli territory, and well, by the time you need that performance we already have a new line of cards

Usually when people say they're getting a big PSU because they're upgrading to dual GTX 580's or something.... nine times out of ten that upgrade never comes.

on this one i only needed about 850watts.

with that being said i had an 850 watt psu and it wasnt enough and died when i maxed my GPU's.
Really? Damn it. I was going going to get 1 295. 600W maybe...

I agree 100%. People tend to suggest wattage overkill way too often. Even with very budget oriented builds.

However, the annoying thing is, for dual GTX 460's or HD 6850's or likewise, you will need a PSU with x4 6-pin connectors included. I have not found a single one under 650W... This is the main reason why I often recommend the XFX 650W PSU's. The Corsair 650W V2 may be a decent unit, however it seems useless when you are going to buy a GTX 560 TI. Unless of course you insist on using the molex connectors for a future GTX 560 TI which are not as relaible as PCI-e/6-pin connectors.

Interesting take but the issue is that there are very few low powered power supplies that appeal to people. Most of them are ugly, aren't modular, aren't necessarily efficient and aren't sexy. After all, we all have parts in our machines which are excessive - it's a hobby for a reason. I don't see why a power supply should be any different. I will admit freely that I got my AX750 because it "felt cool".

heres my ultimate suggestion:

rather be overkill than underkill. aka, better to have a higher powered PSU and be in the clear, than have a psu that cannot boot your hardware. why cut it short when you could spend just a few extra bucks to make sure you will be stable, and have a slight headroom in case you wanted to add like a extra hard drive or something....

I got my EA650 for a few reasons.

1. I had my Autrix 450w which had 8amps on its 12v Rails about to be paired with a GTX460 and I DEFINITELY would of not done that for obvious reasons.

2. I was going to upgrade my CPU/Mobo/RAM at the same time and would require some more juice..

3. It would of felt stupid going from a 450w to a 450w.. No gain for the money. But I did get peace of mind and a POS PSU to pull apart and torture..

I think its more overkill vs just right with a little headroom. It is unlikely that the psu won't be enough to power your system if you are getting good recommendations or if you have a low power system to begin with. Hard drives and stuff barely take any power. I think that what type of gpu you get and if you plan to crossfire/sli plays the most vital role in choosing.
