600w PSU enough?

So not that I want to but I have to suck it up and buy a new PSU, been a long time since I’ve had to buy one that is going to be enough to run my rig, not only that it’s even longer since I’ve had to buy one within limits. Price is an issue but shopping from a particular site is giving me a discount of £30 so thats a plus, on the downside I have only two options from this store - Corsair CX600 or Corsair RM650, firstly, are either of those enough for my rig? I’d like to think the 600w would be enough but like I said it’s been a long time since I’ve had to do any kind of calculation of an ideal PSU but what do you think?

Rig specs are:
AMD 1090T 3.9Ghz
AMD RX480
AIO cooler
4 fans
3 HDD’s + 1 SSD
2x dimm slots in use.

My RM650x is enough for my overclocked 6600k, gtx 1070, 3 hdd, 3 external hdd, 2 ssd and 3 fan.

I doubt my system ever use more than 400W if everything is in 100% usage.

Unless I am reading something wrong, RM650 is a LOT better than the CX600, go for that one. 650W should be enough for your system.

The RM650 is modular, and is gold certified, whereas the other one is only bronze certified.

I personally put more stock into my power supply than anything else in the system, I think it is the most important part to get right. Go as big as you can, but pay MORE attention to the certifications and quality, over wattage alone. I like Seasonic, myself, I run a quality platinum certified PSU.

Remember, your PSU is a part of your computer that you rarely upgrade as much as the other parts, but yet, it is the one thing that can affect everything else you have if it has a problem or is low quality.

Polekatt “it is the one thing that can effect everything…” Yup, sadly why I need an upgrade, I pulled 3 wires out of the 24pin last week and things just haven’t felt right since the repair, not only that I also have a partner who is pregnant and a 3yr old too, so safety is an issue. Funds tell me to go for the CM600 if it would be enough, partner, 3yr old and baby on the way tell me not to get the RM650 but its fully modular! that’s going to be a big plus in the long run, but the cost. It’s hard to justify - The CM600 is suppose to be £67 and the RM650 is suppose to be £99 but this offer would allow me to get £30 off, so I could get the CM600 for £37… Bargain. But then I think I could get the RM650 for £69… that’s a little more than what I’d have to pay for the CM model at standard price so… But funds! :confused:

It’s actually less efficient to have too big of a power supply if you aren’t drawing that much power. You’d only want to go big if you plan to upgrade a lot later and think you’ll need the power. Aim for about 50 to 75%. 400W (to 500 or so) of 650W as described above is a pretty good target. I always go with gold too because I like efficiency.

It’s kind of like driving a car. It’s not very efficient to drive 20 mph or 100 mph, but around 60 mph is good haha

Techtu84 I have Spinalfailed offering me a PSU. But will be quite a while before I can use it. If it would help I can send that to you. I think it’s 600 or 650w. It’s a good one I’ll have to dig messages to see what exactly it was.

Only0neKnight If you have a use for it though you should keep it for that, in my opinion anyways, that’s not to say I wouldn’t put it to good use because it certainly would be put to work right away. what do you mean by it’ll be awhile before you can use it anyways? Like it’s going in some build at some point? Shipping would be a bit pricey too I’d expect?

Those specs will never use more then 450 watts … so 500 would be enough, but 550 to 600 is more safe.

Techtu84 not worried about the shipping. It will prob be next year before I can look at a new desktop build. If it can help I’ll get with Todd and see what we can do.

Techtu84 ahhh, for some reason when I originally read this, I thought your two options, the 600 and 650, were the same price. Totally understand your dilemma there with the funds! If I could afford the increase, I believe I’d go with the gold over the bronze certified one, just for that alone. But with funds being an issue, if Only0neKnight is offering you that one, thats probably your best bet.

I love this place, to see people helping each other like this. :slight_smile:

Techtu84 I would always check what would be the best on this site. Just made good experience with it and as long as you buy a quality PSU you can pick your favorite brand.

That’s the 4th online calculator I’ve used now, this and one other has shown me a figure of around 550w - 600w, the others I thought was crazy high anyway at 700w - 750w :open_mouth:

Only0neKnight I may be mistaken but isn’t Techtu84 on the other side of the pond? If yes its cost prohibitive to ship anything, especially a PSU.

I don’t know if it’s been noted before in the thread, but avoid the RM series from Corsair. They discontinued it for a reason; i.e. failure rates - ask Trainsmash, he’s been affected.

That said if it’s from the RMi or RMx series they’ve shown themselves to be good quality.

Sgt_T8ie I have an RM series, for a while now, and no issues. Like any electronic its the roll of the dice!

Spinalfailed Yeah, I agree, but for anyone buying I’d still steer away from the RM series. I believe for a while Corsair were doing a trade up to the newer RMi(?) series for any RM’s that were RMA’d.

Sgt_T8ie boy that’s a lot of RMs

Spinalfailed Yeah, the shipping, that did cross my mind, in all honesty I have no idea what it would amount to? Like, I wouldn’t even know where to land a guess at how much it might be?
