What features are most important in a power supply?

post #1 of 11
Thread Starter 
Assuming good quality and electrical performance, what features do you find most important in your power supplies?

Efficiency?
Looks?
Modularity?
Cable sleeving?
Cable length?
Low noise levels?
Accessories?



What do you think is MOST important (after quality, preformance, and support)?
post #2 of 11
I would say efficiency just because aesthetics of a power supply don't really matter to me. I would probably never get a modular psu, and almost every quality psu has long enough cables and lower noise levels.

But if we are being technical and not assuming that a quality psu would be quiet and have long enough cables then i would say...

1. Single rail
2. Noise
3. Cable length
4.Efficiency

Also assuming the cables aren't too short to use in a smallish mid tower or smaller (0 PSUs at retail have a problem here),

Noise level is the primary concern by far. Then efficiency I guess?

I don't care much for modular cables or sleeving, but I guess these things are more relevant for larger-capacity power supplies where there are more cables to worry about. I won't ever want multi-GPU setups, so I'd never really be looking at above 400W if anybody actually sold quality power supplies at reasonable wattages.

edit: oh I forgot looks. That's maybe more important than efficiency. As long as it doesn't have an LED fan (or the LEDs can be turned off), then it passes the "looks" category for me.

Me personally.......

Assuming its a good quality unit of course, and at least a solid 80+ or better (efficiency), then I'd have to say looks. Something not a whole lot of brands even offer, but I'd like to see various colors of stickers so its easier to pick a good unit with your color scheme (assuming no LED's obviously here). Take Antec as an example here, most of their current good units are all red stickers. My build is blue / black though. Problem there.

Modular is nice as well (also part of looks if you ask me). Not really a requirement, but at least partially modular is very helpful.

Forgot that in my post. doh.gif

Price, definitely the biggest determining factor. A good unit could hypothetically be one of the best PSU's on the market, but if its more expensive than one that'll still function just as well, then why spend more? Looks can always be changed by modding...price can't.

I'll put them in order for you Phaeds:

Cable length - obviously mandatory that the cables are long enough, so this has to come first. I also don't like it much if they're way too long, but that's better than too short wink.gif

Modularity - I've grown attached to having a modular PSU for a number of reasons, probably wouldn't want to go back to fixed unless the price difference was really substantial. Modularity is worth a premium to me, for sure.

Efficiency - Decent efficiency is reasonably important to me, but I don't have to have Gold ... it's not a huge enough deal to make me rate it above the other concerns. If my current PSU died and you gave me an old low-efficiency but great PSU like a Signature I'd rock that thing rather than spend money on a fancy new Gold unit.

Cable sleeving
- I prefer my PSU to have cable sleeving, for sure ... but it doesn't have to be flashy or even great quality sleeving for me to be cool with it.

Low noise levels
- PSU's are all so quiet nowadays compared to all the other stuff we all have in our cases.

Looks - I prefer a subtle, classy, low-key look. My current PSU is just a very generic glossy black with black sleeving, and I love it. It's what inside that counts with me thumb.gif

Accessories - I could care less what else is in the box besides my PSU and cables.

Redbeard had a thread like this @ [H] a while back... it was full of LOLZ... Single Rail + Quiet + Seasonic type or lolz smile.gif

Full modularity for all product ranges and identical modular interfaces would be nice(and expensive, but nice)... -> universal connectors for the entire product range -> after market cable sets in 3-4 sizes/lengths, standard(ATX), XL(HPTX, XL-ATX, EATX, etc), small(mATX) and micro(ITX).
