Is The CX750M Good Enough?
Is The CX750M Good Enough?
Hey, I'm assembling my first PC and getting the components one by one as I type. Just got my PSU, a CX750M, which I thought was high-end, but it turns out it's not. I'm worried about returning it since I plan to run it with a GTX 1070 and an i7 6700K, aiming to overclock it. Will the PSU be sufficient for this build, or will I need a replacement?
It should work just fine, though it isn't the top choice—it's not the worst either. It's similar to a Ford Focus, although I'd prefer something better. Running it with a 3-year warranty makes me feel more confident. With a system like this, using two HDDs and some fans, you won't exceed 400 watts. Adding overclocking could push it to around 550 watts, but since you're not that aggressive, it should be okay.
Based on my observations, I managed to get around 3.5 good years from a Corsair CX600M, but I’m now starting to encounter problems. This is especially true with an older CPU, so I wouldn’t suggest it for the Haswell/Skylake+ lineup. Similarly, my maximum overclocking seems limited by a power supply bottleneck. If you’re still within the return window, I’d definitely consider it for you.
A Corsair RMx (noting the “x” and its less reliable nature) would offer more stability, use less power, and allow for better overclocking. Here’s a link:

Returning the existing CM750W would likely cost almost nothing compared to the improved PSU. I just placed an order for the RMX two days ago and am excited about the upgrade.
Good luck, mate, cheers.
From my perspective, I managed to extract four solid years from a Corsair CX600M, but I’m now encountering some problems.
Similarly, I think my maximum overclock is being limited by a power supply bottleneck.
If you’re still eligible to return it, I’d definitely consider it if I could.
A Corsair RXM (highlighting the "M", RX is a different, less dependable line) would offer more stability and better overclocking potential while using less power.

It should work fine, though it's not the top choice—it's definitely not the worst. It's like a Ford Focus; I'd prefer something better, but I wouldn't want to risk damaging my PC by running it with it. With a 3-year warranty, it's safe to use. If you run it with two HDDs and some fans, you won't exceed 400W. Adding overclocking to reach around 550W is possible, but you won't be pushing it too hard, so it should be okay.
An evga B2 750 would be a much better choice. The cx750m is the poorest among the CX models, and it didn't receive good feedback.

spat55 shared his thoughts on the matter, saying it should run smoothly without being the absolute best or the worst. He compared it to a Ford Focus, though he’d prefer something better for his PC given the 3-year warranty. With a system like that and two HDDs plus some fans, he expects to stay under 400 watts. Adding a bit of overclocking could push it to 550 watts, but since he won’t be pushing that hard, it should be okay. He also mentioned a personal experience with a 3570k using a 7850HD crossfire on a 550W PSU, which lasted a year before failing and required an RMA. He was pushing around 500 watts and it handled it without issues, even warning him before it failed.

It's similar to a Ford Focus, but I'd prefer something better since running my PC with it feels a bit silly given the 3-year warranty. With a system like that, having 2 HDDs and some fans, you won't exceed 400 watts, then adding overclocking to reach 550 watts shouldn't be too much trouble. It should be okay.

He suggested adding overclocking for around 550W if needed, noting he isn’t pushing it that hard. Woohoopy added his personal experience with the Corsair CX600M, which lasted about 3.5 years before issues started, especially with an older CPU. He also mentioned possible overclocking limits due to a PSU bottleneck. He recommended a Corsair RMx for better reliability and efficiency, shared a link to the product page, and mentioned he’d consider returning an older CM750W if possible. Logainofhades suggested an EVGA B2 750 as a superior option and questioned whether the G2 is a better alternative, noting the difficulty in purchasing PC parts now.
