How Important Is PSU Efficiency? How Much Heat Does A Bronze Rated PSU Make?

I just purchased this PSU. I read the reviews, heard from other users on this forum, and it looked like an absolute steal for that wattage. And considering the PSU was the only major part of my build that I couldn't decide on, I'm quite excited to find a decent quality, 750W in my budget.

I only have two concerns. First, is that this review here specified that the temperature rating was only 40C (every other site that specifies temp rating has it at 50C, so if anyone can confirm that the rating is indeed 50C I would really appreciate it).

Secondly, I'm wondering about heat production. Do bronze rated PSUs generate much heat? And is the heat production actually much of a concern? How much heat is too much heat?

Thanks, this is my first time buying a PSU, and I have no idea what to look for (I've read a few guides and lots of reviews, but some specs aren't discussed much). So if anyone can give me a couple pointers on how cool a PSU should be (and how to best keep it cool), I would be very grateful.

At that price you can get a gold certified from Evga or Corsair. Use the filters on pcpartpicker to find one. You dont want to skimp on a power supply. It could ruin components in your tower at once or over time with varying voltages or even at worst burn the house down!

Let me add as I forgot to mention there is nothing wrong with the power supply you are referring to. A bronze cert is good and considered minimal by most. Heat should not be an issue.

I know I could get a gold rating, but I want the extra wattage, and there's nothing gold rated of decent quality anywhere near the $60 price point. I'm not trying to skimp either, I would be willing to spend more but this looks like a legitimately good PSU. If I'm mistaken about that, let me know.

Really, my question is, would this PSU have any real temperature concerns? It's got a 5 year warranty, and judging from temperature tests in reviews it seems to handle up to 50C fine, just trying to get an idea of how hot a PSU will typically run (at, let's say 85% load). So if someone could give me a quick breakdown on how much heat is expected and how much heat is too much, I'd appreciate it.

At $59 that is a steal. Don't worry too much about the 40c or 50c. Hardwaresecrets pulled 987w out of it at 45c.

The Unit is made by Delta and that is a good thing. You got a very solid unit for the money.

Tier 2. Exactly what's recommended for a higher end gaming computer.

For $60 bucks that is a steal. Your link only told me $100-$120 whicch led me to the gold rating. Was not aware of it only being $60. Like I said earlier your unit is rated for effeciency. Heat should not be an issue.

Yeah, I'm not particularly concerned about whether its 40C or 50C, I just find that inconsistencies have a way of coming back to bite you. I think it's 50C, but I was just asking to see if anyone could confirm (e.g. if someone actually uses this PSU). But for the price, I really don't think there's anything close to as good at 750W, and even if I were to spend $80-90 I just don't think anything can beat the value of the Antec.

Thanks, I really appreciate all responses. If anyone can set me straight on the temp rating for the PSU, I'd appreciate it, but otherwise I think I've heard exactly what I needed to hear.
